In order to make the purpose, technical solution, and advantages of this creation more clear, the following further describes this creation in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this creation, but not intended to limit this creation. In the following, the creation is further explained in combination with the drawings: please refer to FIG. 1 to FIG. 4, which show a schematic diagram of the system layout of this creation, a schematic diagram of image edge detection, a difference diagram of light and dark values of feature points, and a schematic diagram of fluid feature points. As shown in the figure, this creation is mainly composed of a light source providing device 10, an image detection device 20, and a processing element 30. The light source providing device 10 is disposed adjacent to the periphery of a tube 40 In order to provide a light source L to irradiate the tube body 40, since the tube body 40 is a transparent tube body, when the light source L is irradiated on the tube body 40, the light source L will be further transmitted to A fluid 41 in the pipe body 40.

The image detection device 20 is disposed adjacent to the periphery of the pipe body 40 to detect a plurality of feature points FP on a fluid 41 in the pipe body 40, and generates a feature point FP based on the feature points FP. Characteristic data 21. Furthermore, when the light source providing device 10 provides the light source L to the fluid 41, the fluid 41 reflects the light source L to form at least one reflected light RL, and the image detection device 20 receives The reflected light RL enables the image detection device 20 to image a tube image having the fluid. After the image detection device 20 acquires the tube image, the image detection device 20 then An image edge detection process is performed on the pipe body image to detect what is the actual edge E on the two sides of the pipe body in the pipe body image, and then on the two edges of the pipe body. The tube body image in E detects a plurality of feature points FP on the fluid, and the image detection device 20 generates a feature data 21 based on the feature points FP.

One embodiment of the feature points FP may be to use the image brightness of the pipe body image as the feature point FP, for example, when the fluid 41 stops flowing or the pipe 40 does not yet have the fluid 41 flowing. The image detection device 20 can first record the lightness and darkness on the tube 40, and then, when the fluid 41 flows, if a brighter light spot or a darker spot appears on the tube image In the case of dark spots, the image detection device 20 collects the light spots and the dark spots as the feature points FP, and then generates the feature data 21 according to the feature points FP.

Among them, another embodiment of the feature points FP may be to use the ripple of the fluid 41 obtained in the pipe body image as the feature point FP. For example, when the fluid 41 stops flowing, the fluid 41 The plane of the fluid is in a static state, and the image detection device 20 cannot collect any fluid ripples, so it can be judged that the fluid 41 is in a state of stopping flow; and when the fluid 41 flows, the plane of the fluid 41 There will be multiple fluid ripples on the surface. When the flow velocity is fast, the area of the fluid ripple is usually larger, and when the flow velocity is slow, the area of the fluid ripple is smaller. So, the image detection The device 20 can collect these fluid ripples as characteristic points, The feature data 21 is generated according to the feature points FP.

In addition, the image detection device 20 can also collect light points, dark points, and fluid ripples as characteristic points at the same time, which is not limited to one of the above methods.

After the image detection device 20 generates the characteristic data 21 (the characteristic data 21 may include a plurality of the tube body images), the characteristic data 21 is transmitted to the processing element 30. At this time, the processing The element 30 can analyze and calculate the flow velocity and flow rate of the fluid 41 according to the content in the characteristic data 21 to generate a fluid data 31. For example, the flow rate can usually be calculated by the following formula: flow rate (V) = tube length (X) / time (T)

Wherein, the length of the pipe body can be any distance between the first and second pipe images of the feature point FP or the feature points FP, and time refers to the first The time elapsed from the image of the tube body to the second image of the tube body. In this way, it is possible to calculate the flow velocity of the fluid 41. After that, based on the obtained flow velocity, the actual flow rate is derived by the following publicity: flow rate (Q) = flow rate (V) x tube cross-sectional area (S)

In this way, the processing element 30 can calculate the flow velocity and flow rate of the fluid according to the characteristic data 21 to generate a fluid data 31.

When a receiving end 50 receives the fluid data 31, the fluid data 31 can be displayed, so as to provide users with data on the flow velocity and flow rate of the fluid 41.

In this creation, a light source correction element 60 is further provided, which is disposed between the tube body 40 and the image detection device 20. Since the light source L usually illuminates the tube body 40 at an oblique angle, the fluid 41 when the light source L is reflected, it cannot be reflected vertically to the image detection device 20 in a vertical direction, so when the tube body images acquired by the image detection device 20 may cause image deviation, Therefore, when the fluid 41 in the tube body 40 reflects the light source L, the light source correction unit The component 60 corrects the reflected light RL in a forward direction PD, and guides the reflected light RL to the position of the image detection device 20. In this way, the image detection device 20 can form an image without Deviations of these tube body images.

Please refer to FIG. 5 again, which is a schematic diagram of the system layout of another embodiment of the present invention. As shown in the figure, at least one compensation light source device 70 is further provided in the present invention, which is disposed adjacent to the periphery of the pipe body 40 and has a distance from the light source providing device 20. The compensation light source device 70 provides A compensation light CL is irradiated on the tube body 40 to compensate the light source L. The position where the compensation light CL is irradiated on the tube body 40 is different from a position where the light source L is irradiated on the tube body 40. In this way, the compensation light CL and the light source L can be irradiated onto the tube body 40 in a wrap-around manner to provide sufficient brightness to effectively perform subsequent imaging or analysis operations.

Please refer to FIG. 6, which illustrates a flowchart of the steps for measuring the fluid texture of this creation. As shown in the figure, according to the technical contents disclosed in FIG. 1 to FIG. 5, the fluid texture measurement system of this creation can act according to the following fluid texture measurement method to provide a fluid data: Step 101: Use a The light source providing device provides a light source to irradiate a tube; Step 102: Use an image detection device to detect a plurality of characteristic points on a fluid in the tube, and generate a characteristic data according to the characteristic points. Step 103: Use the image detection device to transmit the characteristic data to a processing element; Step 104: Use the processing element to generate the fluid data according to the characteristic data.

Wherein, when the light source providing device provides the light source to irradiate the tube body, the following steps can be further performed: Step 105: using a light source correction element to correct at least one reflected light on the fluid in a forward direction And direct the reflected light to the position of the image detection device; or step 106: using at least one compensation light source device to provide a compensation light to irradiate the tube body The position where the compensation light is irradiated on the tube body is different from the position where the light source is irradiated on the tube body.

After the processing element generates the fluid data, the following steps can be performed: Step 107: Use a receiving end to receive the fluid data to display the fluid data to the outside.

Thereby, the fluid data can be displayed through the receiving end, so as to provide the user with the judgment of the flow velocity and flow rate of the fluid.
